I used to have beautiful teeth and have always been anal about brushing and flossing. My dental problems began at an early age. Just about every back tooth I had, had a filling in it. Upset me because my brother is never brushed his teeth never had a cavity. At the age of 48, the enamel is just about gone and the erosion always starts at the gum line. BTW, I do have a clinical diagnosis of CD. Once the dental problems started on the outside of my teeth, the erosion escalated quickly. I've been replacing my teeth as money permits with implants. Sucks. :(
